MTU Powerpacks To Alstom Railcars

Tognum to supply over 300 drive units to rail vehicles operated by Deutsche Bahn and Netinera

Posted on March 26, 2013


Tognum, a propulsion and power solutions specialist, has announced an order from railcar manufacturer Alstom for the supply of 307 MTU underfloor Powerpacks for the Coradia LINT 41, 54 and 81 railcars. The new railcars powered by the compact underfloor drives from MTU will be circulating on what is known as the Dieselnetz SüdWest network (south-west diesel rail network) in Germany beginning in December 2014.

The MTU Powerpacks, delivering an output of 390 kW, comply with EU Stage 3b emissions legislation and are based on six-cylinder Series 1800 horizontal inline engines from MTU,.

The Coradia LINT 41, 54 and 81rail vehicles are powered by two, three or four Powerpacks, respectively.

The company said the horizontal configuration of the engines makes them highly suitable for use as underfloor drives in rail vehicles, while its compact design also keeps the overall weight of the railcars down, enabling low fuel consumption at high power outputs.

Tognum said that through the use of in-engine technology, particulate emissions have been reduced by around 90% of the maximum level allowed by the previous EU Stage 3a regulations. Combined with engine management, a 5% saving can be made on diesel fuel consumption and lowered CO2 emissions, the company said.

Alstom and Tognum have already joined forces on regional railway projects in Germany, Denmark and the Netherlands.
